In current pre-FFT OFDM (pre-Fast Fourier Transform Orthogonal Frequency-Division) adaptive antenna systems
the CSI (Channel Statement Information) estimation is made in the element-space and the performance may deteriorate due to its poor anti-jamming ability.An adaptive antenna scheme based on beam-space CSI estimation is proposed to improve the accuracy and robustness of the estimation.The simulation results show that a prominent performance improvement can be achieved.In environments with strong interferences
